Note 1: The heating capacity of the CHALLENGER
is based on the test requirements of the U.S.
Department of Energy.
Note 2: The IBR rating is based on a piping and pick
up allowance of 1.15. This allowance should
be sufficient for the standard radiation
requirements for a building load.
Note 3: Based on the given AFUE the CHAL-
LENGER meets the energy efficiency guide-
lines established by Energy Star.
Note 4: Input and output ratings are shown for sea
level applications. The CHALLENGER
automatically derates the input at approxi-
mately 2% for every 1,000 Ft. of altitude. No
alterations to the appliance or burner system
are required.
Note 5: The trailing letter “s” in the model number
refers to CHALLENGER “Solo” Boilers
(heating only). The construction and compo-
nents of these models are identical to the
combination (heating and domestic) models
except the domestic coil is removed from the
heat exchanger along with all associated
domestic components (domestic piping,
domestic sensor, flow switch, domestic
wiring and labeling). The combustion, safety
and efficiency performance is identical to the
combination units.
The following efficiency performance is achieved when the CHALLENGER is operated as
a Boiler according to ASHRAE 103 test procedure
